Abstract

The invention discloses a method for manufacturing a workpiece and the workpiece. The method includes: forming an inner cavity core by using a core material; assembling joint parts on the inner cavity core; A metal thin-walled layer is formed on the surface; the inner cavity core is removed to form a metal thin-walled cavity part. In the present invention, the metal thin-walled cavity part includes joint parts coated inside it, which is convenient for the installation of the thin-walled part; Cavity complexity limitation; the metal thin-walled layer is attached to the surface of the inner cavity core, which can be as thin as possible while meeting the strength requirements, overcoming the wall thickness limitation and metal applicable material limitation in the existing manufacturing process; Simultaneously, the preparation process is simple and the manufacturing cost is reduced.

Description

A workpiece manufacturing method and workpiece technical field [0001] Embodiments of the present invention relate to the technical field of thin-walled parts processing, and in particular, to a method for manufacturing a workpiece and a workpiece. Background technique [0002] For water cooling or air cooling or special elastic requirements in engineering applications, it is necessary to manufacture thin metal walls such as cold plates and cold pipes. Cavity parts. Water-cooled parts have water or ventilation inside, and the outer wall of the parts needs to be as thin as possible under the premise of meeting the strength requirements. In different application scenarios, the shape of the cavity inside the shell may also be different. [0003] There are three main methods of manufacturing metal thin-walled cavity parts by traditional technology: 1. five-axis machine adds back plug sealing [0005] Based on the traditional machining, it is necessary to extend the cutter in...
